So I have 99 EX VTec coupe; changed the exhaust from headers to muffler. Started myself but couldn't get the manifold off without snapping the bolts so I outsourced. They told me I needed an upstream 02 sensor, I told them I'd do it myself. They through away the old one and now I've been searching wreckshops and pull-a-part and can't find a 2 prong/pin sensor cause everyone went to 4, can't order it either. So I was wondering if you had an old one or access to one that I can pay you for? S I mean suggested bypassing the 02 with a chipped out ECU. Help!!!
